TERRAZZQ STRIP.

Application filed June 3,

The subject of this invention is a novel and improved dividing or pattern forming strip such as is used for wall structures, for

instance, terrazzo floors, where a variegated design is to be exposed on the finished structure. For convenience, therefore, the new strip will be referred to hereinafter as a terrazzo strip, and the advantages of the same will be described in connection with the laying of terrazzo floors. I

A terrazzo strip, as is well known in the art, laid during the laying of the floor, and forms an inbuilt part of the completed floor.

One of the objects ofthe present invention is to provide a terrazzo strip, which may be cheaply formed, as by a stamping operation, for instance out of thin sheet brass; and which, while having portions displaced from the general plane of the strip, for interlocking with the plastic material on one or both sides of the strip, will at the same time present these displaced portions in such wise that these displaced portions will not result in the production of other strip portions presenting localized points of weakness.

Such displaced portions may be provided as tabs cut from the strip, at points removed from the edges of the latter, and bent at an angle to the plane of the strip to establish an opening alongside each tab; and it is another object of the present invention to cut and bend these tabs so that one or more edges of the opening, or the fiat of the tab when bent away from the opening, or both, shall be at an angle to both the vertical and horizontal when the strip is positioned in the floor.

Since ,a terrazzo strip acts not only as a divider or partition wall relative to different batches of plastic material, but also as a means for interlocking such batches, a structure according to the present invention not only provides openings through the strip, for receiving portions of plastic material on opposite sides of the strip, whereby the strip may interlock with such plastic material, butalso provides tabs or openingedges or both, at angles both to the vertical and horizontal, for compounding the interlocking action; and at the same time said structure, if constructed to satisfy the first mentioned object, as is preferable, also has the openings faced at their bottoms by parts 1927. Serial No. 196,229.

of the strip the integrity of which parts, due to their transverse dimensions, or to the shapes of the openings defining the upper edges of said parts, or both, may be absolutely depended on.

Various other objects and advantages of the invention than those hereinabove mentioned will be specifically pointed out or will be apparent hereinafter in the courseof the below detailed description of the forms of the invention shown, in the accompanying drawing, as preferred ones of the various possible embodiments of the invention; it being understood, naturally, that such forms are merely illustrative of some of the many possible combinations and arrangements-of parts well calculated to attain the objects of the invention.

In said drawing:

Fig. 1 is a view in side elevation showing a portion of a terrazzo strip incorporating one form of the invention;

Fig. 2 is a longitudinal section, taken on line 2-2 of Fig 1;

Fig. 3 is a view similar to Fig. l, but showing another form of the invention;

Fig. 4 is a transverse section, taken on line 4:4; of Fig. 3; and

Fig. 5 is a top plan view of the parts shown in Figs. 3 and 4.

In all these views, the terrazzo strip is indicated at 6.

In the case of Figs. 1 and 2, the strip is provided, at suitable intervals along the length thereof, with cut-out portions, as illustrated. In the present case, two triangular tabs 7 and 8, are provided by the displaced strip material at each cut-out location. Both tabs are bent away from the plane of the strip, thereby to establish the triangular opening 9. In the present case, tabs 7 and 8 are bent in opposite directions and to project on opposite sides of the strip and perpendicular thereto.

According to this construction, an open ing is provided having edges inclined to the horizontal as well as to the vertical, to wit, the edges 9; and at the same time such opening is faced at its bottom by a part 6' of the strip, of such a transverse dimension as to insure the permanent integrity of said part 6 with the remainder of the strip. 7

In the case of Figs. 3, 4 and 5, the strip 6 is also provided, at suitable intervals along the length thereof, with cut-out portions, as

illustrated. In the present, two triangular tabs 10 and 11 are provided by the dis placed strip material at each cut-out location. Both these tabs, too, are bent away from the plane of the strip; and said tabs are bent in opposite directions and to projeet on opposite sides of the strip perpendicular thereto. Here, however, the opening 12 established, is substantially of diamond outline,

According to this construction, an opening is provided having all. its edges inclined to the vertical as well as to the horizontal, and. at the same time the tlats of the tabs are inclined to each other and also to the vertical as well as to the horizontal. Nevertheless, here again, the opening 12 is faced at its bottom by a part (5 of the strip, which part 6 is so shaped, due to the inclinations oi the two lower sides of the opening 12, as to insure the integrity of? such part 6" with the remainder of the strip.

It will be clear that the strip of Fig. 1 may be so cut that triangular tabs corresponding to the tabs 7 and 8 maybe bent from the strip to form the edges 9 ()1 the opening 9, instead of the tabs 7 and 8 as illustrated; so that, when desired, the form of the invention shown in Fig 1 may have incorporated therein the tab-inclination structure characteristic of Fig, 3.

Inasmuch as many changes could be made in the above constructlons, and many apparently widely different embodiments of the 3" invention could be made without departing from the scope thereof, it is intended that all matter contained in the above descrip tion or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language contained in the following-claim is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

I claim:

A strip of the kind described having a plurality of pairs of tabs partially severed from the strip and extending from the strip at right angles, each pair of tabs having its individual members extending in opposite direction from the strip and together establishing an opening intermediate the edges of the strip, the bases of each pair of tabs being connected to the strip in obtuse angular relation.

In testimony whereof I affix my signature.
